VILLIAM F. TORREY, OF AUBURN, ASSIGNOR OF ONE-HALF TO ZECI'IARIAH R.TUCKER, OF PROVIDENCE, RHODE ISLAND.

ERASER-CASE'.

SPECIFICATION forming part of Letters Patent No. 505,733, datedSeptember 26, 1893.

Application filed May 4, 1893. Serial No. 472,980. (No model.)

.'Zo all whom it may concern.'

Beit known that I, WILLIAM F. TORREY, of Auburn, in the county ofProvidence and State of Rhode Island, have invented certain new anduseful Improvements in Eraser- Cases; and I hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanyng drawings, forming part of this specifica-Ion.

This invention has reference to improvements in eraser-cases.

The object of the invention is to so construct an eraser-case that,while being perfectly protected, the eraser may be drawn forward fromtime to time and,when completely used, can be replaced by a new one.

The invention consists in the peculiar and simple construction of thecase and the combination therewith of the eraser-bar, as willhereinafter be more fully described and pointed out in the claims.

Figure l represents a side view of the case with a portion of theeraser-bar extending therefrom. Fig. 2 represents a cross-sectional viewof the case taken on a line @-5, Fig 1. Fig. 3 represents a view of thecasein the open position, the eraser-bar being shown therein.

Similar numbers of reference designate corresponding parts throughout.

As heretofore constructed cases for containing and protectingeraser-bars of erasive rubber have been constructed of boxes, or tubes,open at the end from which a portion of the eraser-bar extended. Whenthat portion of the bar extending from the case became worn down it wasdifficult and often impossible to withdraw the eraser-bar from the case,resulting in considerable loss both in the eraserbar and the case whichwas not adapted to receive a second eraser.

In carrying my invention into practice it has been my desire to providea case for containing and protecting the ordinary eraserbar and to allowof its gradual extension therefrom from time to time as the outer endbecomes worn and finally to allow of the insertion of a new eraser whenthe first has been used; to this end I have constructed a caseconsisting of the parts 4. and 5 each of `which has two sides 6 and 7, aclosed edge 8 or 9 and a closed end 10 or l1, the opposite ends beingleft open.

The part 4, or base-portion, of the case is of a size to receive andretain the eraser-bar 12 of the usual construction. Near the open `endof this part the edge 8 is bent inward to form an impinging tooth I3 andportions of the sides are concaved to form sockets 14, the 6o convexparts of which on the inner surfaces of the sides 4L tend to hold theeraser-bar.

The part 5, or sheath, into which the base 4L shuts, is pivoted at theclosed end to the closed end of the base. This part has an impingingtooth l5 bent inward from the edge 9, and the sides 7-7 are furnished ontheir inner surfaces with convex-catches 16-16 which engage in theconcavities 14 of the base and tend to hold the two parts together at 7othis end.

The eraser-bar l2 is securely held between the sides 6--6 of the baseand is gripped by the impinging teeth 13 and 15. When the exposedportion becomes worn the parts of the case may be opened and the erasermoved along to expose a new portion until the whole bar has been used,when a new bar may be readily inserted.

Having thus described my invention, I 8o claim as new and desire tosecure by Letters Patentl. The combinatioinin an eraser-case, of thebase provided with the holding sockets, of the sheath pivoted to thebase and provided with the convex catches and impinging tooth, allsubstantially as herein shown and dey, scribed.

2. The combination with the base 4 having the sides 6-6 furnished withconcavities 9o l4-14E, the closed end l0 and the closed edge 8 havingthe impinging tooth 14: bent inward therefrom, of the sheath 5, pivotedto the base, having the sides 7-7 furnished with the catches l6-l6, theclosed end 1I, and the 95 closed-edge 9 having the impinging tooth l5bent inward therefrom, as and for the purpose described.

In witness whereof I have hereunto set my hand.
